Honichi dialect does not share some features peculiar to other Kyushu dialects such as ka-adjective and batten particle. Buzen-Oita dialects do not use to particle. An emphasizing particle cha is used in Honichi dialect and Yamaguchi dialect.

In the pitch accent, Miyazaki dialect and Buzen-Oita dialects are very different. Buzen-Oita dialects use Tokyo-type accent as well as Chugoku dialect, but Miyazaki dialect is noted for its monotony accent as well as some dialects classified the Hichiku dialect. Another striking difference between Miyazaki and Buzen-Oita dialects is the particle meaning "because": while Miyazaki dialect uses kara or kai, Buzen-Oita dialects use ken or kee or kii as well as Chugoku, Shikoku and Hichiku dialects.
